You are the manager of a restaurant for a fast-food franchise. Last month, the mean waiting time at the drive-through window for branches in your geographical region, as measured from the time a customer places an order until the time the customer receives the order, was 3.6 minutes. You select a random sample of 64 orders. The sample mean waiting time is 3.85 minutes, with a sample standard deviation of 0.8 minute. At the 0.05 level of significance, is there evidence that the mean waiting time is greater than 3.6? What is the p-value for this test? (Round to four decimal places.)
